Sydneykid, Money sent. Cant PM you cause box is full. PM me for postage details.

According to a post by someone (can't remember who) they found the clicking to be gears in the climate control playing up. The photo is one that they posted up. I seem to remember them saying it took 6-7 hours to get to it properly as you have to pull the whole dash out (speedo, vents, etc.)

I got my mechanic friend to do the replacement for me, but I think the best way to check the belt is to get a mechanic to take off the cam gear cover and crank angle sensor unit to inspect the belt condition. I think in my case it was more to do with the bearings in the 2 pulleys as they sounded like a cement mixer when you spun them. It isn't a cheap exercise to replace all these components, especially when you have labour costs to consider, so I would probably get a mechanic to check it for you to be honest. This way you won't end up replacing something that might not be broken. I think the parts cost me about $500 and there will be a few hours labour involved. My car had come up to 100000km when I bought it so I had already factored this into the equation. My car is a 95 r33 so I think it's around the same age as yours, going from your sig.

I believe that this is your timing belt idler or tensioner pulley bearings starting to show their age. My car had this exact noise in the same rev range and when I replaced the timing belt and pulleys, the noise was gone. If your car is coming up to 100 000 km then I would get them replaced pronto.

They unplugged the wrong thing. In my r33 there are 2 devices under the dash, on the left hand side of the steering column. Unplugging one of them took out the beeper, but also took out the windows, etc.. The other one is just the beeper and should be able to be unplugged with no hassles. Its view is obscured by the first device, but you shouldn't have to remove any panels to get to it.
